DIP Switch Setting
Rosslare readers that support OSDP operation are compatible with most OSDP commands. The reader address is set
using DIP switches on the back of the reader.
The DIP switch settings are as follows:
3.6.2.1. DIP Switches 1 to 4
These switches set the address of the reader for OSDP protocol.
DIP Switch 1 is MSB and DIP switch 4 is LSB. The address is the DIP switch state +1.
Examples:
•
All the DIP switches in Off position, state is = 0 => address = 2 (in AxTraxNG/AxTraxPro Access Control
Management Software)
•
DIP switches 1, 3, 4 in On position and 2 in Off position, state is = 0x0B => address = 0x0C = 13
In every system, each board’s ID must be unique.
The ID is set only in the initialization phase. The system does not synchronize if an existing board’s ID is
changed or if a board is added or removed. The system must be initialized to synchronize the IDs.
3.7. Readers and Cable Length
Readers are supplied with cables having a limited length. The color of the cable cover represents the cable’s
functionality according to the Wiegand and OSDP standards.
If you wish to extend the cable distance, make sure you use the correct cable according to the cable color.
Power to the OSDP readers is to be taken from the reader +12 V outputs.
Do not connect more than two readers per each +12 V output.
